We love the miniature Coptis japonica var. dissecta in full seed now. This dwarf, evergreen, woodland-growing member of the Ranunculus family (Clematis, Helleborus), has small white flowers in the winter, but we adore the seriously cute seeds heads that are adorned in March and April. Not only is this Japanese endemic a cool garden plant, but it’s highly prized as a medicinal plant, thanks to chemicals harvested from its roots, which are used to treat an array of ailments, from infections to pain, dysentery, fevers, and much more. Hardiness Zone 5a-8b.
